I slept 6 hours last night 12:30 - 6:30. My naps at 11am and 3pm went ok, if a bit shallow, naps at 7pm and 11pm went the full time, but no real sleep. This is really to be expected at this point I suppose.
My back has been tight the whole day. Also a bit of neck/headache pain. It is way to early for any of this to be attributable to the sleep thing. I must have just jimmied things up by sleeping on it funny during my normal sleep.
